OBJECTIVE Glioblastoma (GBM) is the most common and deadly malignant primary brain tumor. Better surgical therapies are needed for newly diagnosed GBMs that are difficult to resect and for GBMs that recur despite standard therapies. The authors reviewed their institutional experience of using laser interstitial thermal therapy (LITT) for the treatment of newly diagnosed or recurrent GBMs. METHODS This study reports on the pre-LITT characteristics and post-LITT outcomes of 8 patients with newly diagnosed GBMs and 13 patients with recurrent GBM who underwent LITT. RESULTS Compared with the group with recurrent GBMs, the patients with newly diagnosed GBMs who underwent LITT tended to be older (60.8 vs 48.9 years), harbored larger tumors (22.4 vs 14.6 cm3), and a greater proportion had IDH wild-type GBMs. In the newly diagnosed GBM group, the median progression-free survival and the median survival after the procedure were 2 months and 8 months, respectively, and no patient demonstrated radiographic shrinkage of the tumor on follow-up imaging. In the 13 patients with recurrent GBM, 5 demonstrated a response to LITT, with radiographic shrinkage of the tumor following ablation. The median progression-free survival was 5 months, and the median survival was greater than 7 months. CONCLUSIONS In carefully selected patients with recurrent GBM, LITT may be an effective alternative to surgery as a salvage treatment. Its role in the treatment of newly diagnosed unresectable GBMs is not established yet and requires further study.

Abstract INTRODUCTION Glioblastoma (GBM) is uniformly associated with a poor prognosis and inevitable recurrence. Management of recurrent GBM remains unclear, with repeat surgery often employed with varying degrees of success. We evaluated the efficacy of Laser Interstitial Thermal Therapy (LITT) for recurrent GBM when compared to a carefully matched cohort of patients treated with repeat surgical resection. METHODS A retrospective single-institution database was used to identify patients who underwent LITT or surgical resection of recurrent GBM between 2014-2019. LITT patients were matched with surgical resection patients according to baseline demographics, comorbidities, tumor location, and eloquence. Subgroup analysis matching similar patients for tumor volume was also completed. Overall survival (OS) and progression-free survival (PFS) were the primary endpoints. RESULTS A LITT cohort of 20 patients was matched to 50 similar patients who underwent repeat surgical resection. Baseline characteristics were similar between both cohorts apart from tumor volume, which was larger in the surgical cohort (17.5 cc vs. 4.7 cc, p< 0.01). On long-term follow-up, there was no difference in OS (HR, 0.72; 95%CI, 0.36-1.45) or PFS (HR, 0.67; 95%CI, 0.29-1.53) between the LITT and surgical cohorts when controlling for tumor volume. Subgroup analysis of 23 LITT patients matched according to tumor volume with 23 surgical patients with similar clinical characteristics also found no difference in OS (HR, 0.66; 95%CI, 0.33-1.30) or PFS (HR, 0.58; 95%CI, 0.90-1.05) between the cohorts. LITT patients had shorter length of stays (1 vs. 4 days, p< 0.001) and a higher rate of home discharge (84% vs. 67%, p=0.172) compared to the surgical cohort. CONCLUSION After matching for demographic, clinical, and tumor characteristics, there was no difference in outcomes between patients undergoing LITT compared to surgical resection for recurrent GBM. LITT patients had similar survival outcomes yet shorter hospital stays and more favorable dispositions, potentially mitigating post-treatment complications.

Abstract There have been publications that propose the use of laser interstitial thermal therapy (LITT) as a viable alternative to craniotomy for the treatment of glioblastoma (GBM). The aim of this study was to retrospectively compare outcomes after LITT versus craniotomy for patients with recurrent GBM. To adequately match the cohorts, we included only pre-treatment tumor volumes of under 15 cc. We retrospectively collected data on all patients presenting with recurrent GBM, with a recurrence volume under 15 cc. These patients were either treated with LITT or craniotomy by the senior author. Data included demographics, tumor location and volume, tumor markers, perioperative complications, re-initiation of adjuvant chemotherapy, and long-term follow up data. We performed 23 LITT treatments and 34 craniotomies for recurrent GBM in patients that met selection criteria. There was no significant difference in the patients’ age, tumor volume (6.38 for craniotomy versus 5.765 cc for LITT), location, and post-procedure KPS. Patients that underwent LITT had significantly reduced inpatient stays in comparison to craniotomy (1.7 versus 4.2 days). They also had less perioperative complications (13.0% versus 32.3% for craniotomy). It was found that 28 out of the 34 patients that underwent craniotomy were able to undergo adjuvant therapy; in comparison, 15 out of the 23 patients who underwent LITT had undergone adjuvant therapy. Of these patient’s that underwent adjuvant therapy, 87% of patients were able to receive bevacizumab or a clinical trial versus 42% after craniotomy. Progression-free survival (PFS) and overall survival (OS) after procedure were similar for LITT versus craniotomy, respectively: % PFS-survival at 6 months = 23.5% versus 21.7%. Overall survival did not significantly differ at 9 months versus 9.9 months respectively. LITT appears to be safe and may be as efficacious as craniotomy in achieving progression free survival for small to moderate volume recurrent GBM.

Laser Interstitial Thermal Therapy

Abstract INTRODUCTION Laser Interstitial Thermal Therapy (LITT) is a novel treatment modality that has been used for an array of intracranial pathology. In the current manuscript, we sought to conduct a systematic review and meta-analysis to summarize all available literature to date, on outcomes of patients with recurrent GBM (r-GBM) undergoing LITT, pooling together quantitatively the overall survival and progression-free survival data. METHODS A comprehensive literature search was performed to retrieve all studies investigating overall survival, post-procedure survival, and progression-free survival outcomes of patients with r-GBM undergoing LITT. All statistics were pooled together by the meta-analysis of the mean using a weighted random-effects (RE) or fixed-effect (FE) model. RESULTS Eleven studies were included in the final cohort, representing a total of 134 patients with rGBM. The pooled mean age of the cohort at the time of recurrence diagnosis was found to be 56.7 ± 4.56 while 41% of the cohort were females. For the delivery of LITT, two studies utilized neodymium-yttrium aluminum-garnet laser (Neodp-YAG Laser), three studies utilized the Visualase system, five studies utilized the Neuroblate system, and one study used both the Neuroblate and the Visualase system. A total of eight studies with 107 patients had available data for overall median survival. The pooled overall survival was found to be 18.6 months (95%CI 16.2-21.1). A total of six studies with 93 patients had available data for post-LITT survival. The pooled post-LITT survival was found to be 10.1 months (95%CI 8.8-11.6). A total of eight studies with 119 patients had available data for progression-free survival. The pooled progression-free survival was found to be 6 months (95%CI 5.3-6.7). CONCLUSION LITT is a novel minimally invasive procedure which, when used with optimal adjuvant therapy, may confer survival benefit for patients with r-GBM.

We examined the efficacy of five commonly used drugs, teniposide (VM26), cisplatin (CDDP), cyclophosphamide (CPM), doxorubicin (DOXO), and vincristine (VCR) in a retrospective analysis of 44 clinical trials of induction chemotherapy for stage IV neuroblastoma patients newly diagnosed at older than 1 year of age. Dose intensity (DI) of each drug was calculated as milligrams per square meter per week. Linear regression analyses showed that the Dls of VM26 and CDDP had the greatest influence on clinical outcomes (ie, proportion of major response, median survival, and median progression-free survival [PFS]), while those of CPM and DOXO were less significant. VCR had no influence on the three clinical end points. Although many protocols extended treatment to more than 1 year, none of these end points correlated positively with the duration of therapy. Twenty-one weeks appeared adequate for achieving superior response, median survival, and median PFS. These results suggest that maximal dose intensification of selective drugs over a short duration may improve the outcome of patients with poor-risk neuroblastoma.

Abstract BACKGROUND Laser interstitial thermal therapy (LITT) is being used for the treatment of recurrent glioblastoma multiforme (GBM). Lesions can be treated using 1 or multiple LITT fibers depending on the preference of surgeons. Usually, more fibers are needed for coverage of larger tumors. OBJECTIVE To investigate and analyze how tumor size affected the number of LITT fibers used. METHODS This is a retrospective review of patients undergoing treatment of recurrent GBM. Patients were treated with up to 4 LITT fibers for adequate tumor coverage. Patient demographics, tumor characteristics, length of stay, complications, and biopsy results were recorded. RESULTS A total of 43 cases were treated using LITT, and of these cases, 31 consisted of contiguous lesions. We used more fibers to treat larger tumor volumes. On average, for each 5 cc of tumor volume, a fiber was added for proper coverage (P = .554). Complications and length of stay were similar across the groups (P = .378, P = .941). CONCLUSION LITT can be used for the treatment of recurrent GBM. For each 5 cc of tumor volume, a LITT fiber can be added to the treatment plan.

e13538 Objective: A single institution retrospective evaluation of nivolumab following disease progression on bevacizumab in adults with recurrent glioblastoma (GBM) with an objective of determining progression free survival (PFS). Background: There is no accepted therapy for recurrent GBM after failure of bevacizumab. Methods: 16 adults, ages 52-72 years (median 62), with recurrent GBM were treated. All patients had previously been treated with surgery, concurrent radiotherapy and temozolomide, and post-radiotherapy temozolomide. Bevacizumab (with or without lomustine) was administered to all patients at first recurrence. Patients were treated with nivolumab only (3mg/kg) once every 2 weeks at second recurrence. One cycle of nivolumab was defined as 2 treatments. Neurological evaluation was performed bi-weekly and neuroradiographic assessment every 4 weeks. Results: A total of 37 treatment cycles (median 2) were administered of nivolumab in which there were 14 Grade 2 adverse events (AEs) and Grade 3 AEs in 2 patients. No Grade 4 or 5 AEs were seen. Following 1 month of nivolumab, 7 patients’ demonstrated progressive disease and discontinued therapy. No patient demonstrated a response though 9 patients demonstrated neuroradiographic stable response. Survival in the entire cohort ranged from 2 - 6 months with a median of 3.5 months (CI: 2.8, 4.2). Median and 6-month PFS at 6 months was 2.0 months (range 1-5 months; CI: 1.3, 2.7) and 0% respectively. Conclusions: Nivolumab salvage therapy demonstrated no survival advantage in patients with recurrent bevacizumab refractory GBM emphasizing a continued unmet need in neuro-oncology.

Object The object of this study was to investigate the safety and clinical responses of immunotherapy targeting the WT1 (Wilms tumor 1) gene product in patients with recurrent glioblastoma multiforme (GBM). Methods Twenty-one patients with WT1/HLA-A*2402–positive recurrent GBM were included in a Phase II clinical study of WT1 vaccine therapy. In all patients, the tumors were resistant to standard therapy. Patients received intra-dermal injections of an HLA-A*2402–restricted, modified 9-mer WT1 peptide every week for 12 weeks. Tumor size, which was obtained by measuring the contrast-enhanced area on magnetic resonance images, was determined every 4 weeks. The responses were analyzed according to Response Evaluation Criteria in Solid Tumors (RECIST) 12 weeks after the initial vaccination. Patients who achieved an effective response continued to be vaccinated until tumor progression occurred. Progression-free survival and overall survival after initial WT1 treatment were estimated. Results The protocol was well tolerated; only local erythema occurred at the WT1 vaccine injection site. The clinical responses were as follows: partial response in 2 patients, stable disease in 10 patients, and progressive disease in 9 patients. No patient had a complete response. The overall response rate (cases with complete or partial response) was 9.5%, and the disease control rate (cases with complete or partial response as well as those in which disease was stable) was 57.1%. The median progression-free survival (PFS) period was 20.0 weeks, and the 6-month (26-week) PFS rate was 33.3%. Conclusions Although a small uncontrolled nonrandomized trial, this study showed that WT1 vaccine therapy for patients with WT1/HLA-A*2402–positive recurrent GBM was safe and produced a clinical response. Based on these results, further clinical studies of WT1 vaccine therapy in patients with malignant glioma are warranted.

PURPOSE To evaluate the efficacy and toxicity of combination chemotherapy with bleomycin, vincristine, mitomycin, and consecutive low-dose (CLD) administration of cisplatin (CLD-BOMP) for patients with recurrent cervical carcinoma. PATIENTS AND METHODS Ninety patients with recurrent cervical carcinoma and no prior chemotherapy were enrolled onto this study. The median age was 56 years. Eighty-seven of the 90 patients had received prior radiotherapy. The CLD-BOMP regimen was bleomycin 5 mg infused continuously days 1 through 7; vincristine 0.7 mg/m2 bolus day 7; mitomycin 7 mg/m2 bolus day 7; and cisplatin 10 mg/m2 infused over 4 hours days 1 through 7. The treatment was repeated at 3-week intervals. RESULTS All 90 patients were assessable for response, toxicity, and survival. After a median of four cycles (range, two to 10 cycles), we observed objective responses in 68 patients (76%), with 25 (28%) complete responses (CRs) and 43 (48%) partial responses (PRs; 95% confidence interval (CI), 66 to 85; 18 to 38; 37 to 59, respectively). Median survival for all 90 patients was 24.3 months (range, 2.3 to 100 months). The median survival for patients who achieved CR, PR, no change (NC), and progressive disease (PD) were not reached (NR), 23.6, 8.2, and 6.4 months, respectively. The median progression-free survival for patients who achieved CR and PR were NR and 12.3 months, respectively. There was no significant nausea or vomiting, nephrotoxicity, or pulmonary toxicity, which was attributable to the CLD-cisplatin and the adequate dosing schedule of bleomycin. The reduced toxicities allowed this regimen to be administered at the projected dose-intensities. CONCLUSION The CLD-BOMP regimen has significant antitumor activity with markedly reduced toxicity.

Abstract Background: In this prospective study, we compared VRD with Ld as induction therapy for newly-diagnosed Multiple myeloma patients. The primary objective of this study is to compare the progression-free survival in the 2 arms. Methods: Between September 2014 and Oct 2016, 144 patients have been recruited and randomly assigned to receive 4 cycles of either Bortezomib 1.3 mg/m2 SC on days 1, 8, 15 and 22 with Lenalidomide 15mg/day from day 1 to 14 (Arm A) or Lenalidomide 25 mg/day from day 1 to 21 (Arm B). Patients in both arms received oral dexamethasone 40 mg on days 1,8,15 and 22. Both treatment regimens were 28-day cycles. All patients received 75 mg aspirin daily, acyclovir prophylaxis and monthly zoledronic acid. Response assessment was done at the end of the 4th cycle using the International Myeloma Working Group (IMWG) uniform response criteria. The study was approved by the Institute Ethics Committee (Ref IEC/NP-264/01-08-2014, RP-7/2014). Results: These are the results from an analysis of 143 patients (arm A-74, arm B-69). Baseline characteristics of patients were similar in both arms with respect to age, gender, ISS and DS stage, immunoglobulin subtype and serum LDH. Patients' median age is 56 years (range 31-70) in arm A and 52 years (range 28-69) in arm B. Gender M/F: Arm A 54/20 and 43/26 in arm B. ISS stage III 51 (68.9%) arm A vs 44 (63.8%) arm B. Serum LDH raised to >250 u/L was observed in 25 (44.6%) vs 31 (52.5%) in arms A and B, p=0.4. Revised staging including ISS and serum LDH at baseline: stage III 47 (81%) and 37 (65%) in arms A and B respectively. 14 (18.9%) and 19 (27.5%) of patients had light chain myeloma in arms A and B respectively. Overall response rates (sCR+CR+VGPR+PR) is 78.4% vs 73.9% in arms A and B respectively, p=0.6; sCR + CR 21 (28.4%) and 21 (30.4%) respectively, p=0.86. Median follow-up 17.1 months (range 1 to 33). Median overall survival (OS) is 30.2 months (95% CI 28.2 to 32.2) and 28.6 months (95%CI 26 to 31.3) in arms A and B respectively, p=0.3. Median progression-free survival (PFS) was 27.8 months (95%CI 25.4 to 30.2) and 28 months (95%CI 24.6 to 31.4) respectively, p=0.3. Estimated one-year OS is 88% vs 85% in arms A and B, and PFS 83% vs 72%, respectively. Grade 3 anemia occurred in one patient in arm B, and grade 3 deep vein thromboses in one patient in arm A. One patient in arm A developed grade 4 myelosuppression leading to therapy change at the end of the first cycle. Conclusion: In this analysis - response rates and median progression-free survival are similar in both arms. Disclosures No relevant conflicts of interest to declare.
